Ceramic Tile Cost Calculator

The material and firing cost of a batch of hand-made tiles, per tile and per square metre.

Tile length mm

Tile width mm

Grout joint mm

The joint the tiles will be laid with. Used for the area one tile covers on a wall.

Wet clay per tile g

Weigh a slab before cutting rather than estimating from the finished tile.

Clay price per kilogram

Glaze slurry per tile ml

About 40 to 60 millilitres per 100 square centimetres at a working thickness.

Glaze price per litre of slurry

A slurry at a specific gravity of 1.45 contains about 40 percent dry material by weight. The glaze mixing calculator gives the dry figure if you prefer to cost it that way.

Tiles in one kiln load

Flat tiles pack badly, so a shelf holds far fewer than its area suggests. Use a figure you have really achieved.

Cost of both firings for one load

Bisque plus glaze firing. The kiln cost calculator gives the electricity figure.

Your working time per tile min

Rolling, cutting, cleaning, glazing and finishing. Measure it over a batch rather than guessing one tile.

Your time per hour

Breakage and second allowance %

Ten to twenty percent is realistic for flat work, because one flawed tile spoils a uniform run.

Markup on cost times

Two to three times the total cost is usual for handmade production work.
